system with molar ratio 0.75/0.25 were prepared at room temperature by sol–gel wet chemical route. The as-prepared samples were annealed at 500, 700 and 850 °C for 3 h. Structural parameters of annealed powdered samples were determined by X-ray diffraction (XRD). The crystallite size was calculated using Debye–Scherrer formula as well as Williamson-Hall relation and then compared. Other structural parameters such as lattice parameters, micro-strain, dislocation density and activation energy were also estimated. The functional groups present in the samples were confirmed by Fourier transform infrared spectroscopy (FTIR).
